BALL-VALVE STOP.

Application filled October 22, 1923. Serial No. 669,962.

T 0 all whom t may concern.'

Be it known that I, JAMES C. RYAN, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Ball- Valve Stops;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures oit' reference markedthereon, which form a part of this specification.

This invention relates to flush valve mechanism and particularly tomeans for controlling the amplitude of movement of the valve for theinlet port. The primary object of the invention is to provide a novelinexpensive easily applied means which can be readily associated with aconventional form of flush valve. mechanism and be so regulated that thevalve can only move off its seat a determined amount. In other words itsamplitude of movement may be controlled.

The novel construction of the invention will be clearly apparent byreference to the following description in connection with theaccompanying drawings, in which- Fig. 1 is a sectional view through aflush valve mechanism constructed in accordance with my invention, partof the supply pipe being shown in elevation, and

Fig. 2 is a disassociated view of the cap to be applied to the flushvalve pipe with the regulating device for determining the amplitude ofmovement of the valve.

The flush valve consists of a housing 1 having a valve seat 2 thereinwhich controls the effective port area of the inlet port 3. Thedepending threaded pipe portion 4f being adapted to be connected to anysuitable source of supply. A discharge nozzle 5 is above the inlet port3 and is adapted to discharge into the tank as will be readilyunderstood. A reciprocatory valve 6 is mounted in the valve housing 1and is adapted to move o-nto and oil the seat 2. rIhe valve 6 has a.slot 7 through which a pivoted lever 8 extends. One end of the lever ispivoted to the bracket 9 and the other end is connected to an elbowlever 10` by a link 11, the elbow lever 10 being pivoted to a bracket 12connected to a float stem 13 on the outer end of which is a float 14adapted to rise and fall with the liquid within the tank so that whenthe float 14 rises the valve 6 will seat and when the float falls thevalve will unseat. All of this construction is old and well known andconstitutes a part of the conventional type of Hush valve mechamsm.

It is desirable to control the amplitude of movement of the valve 6 andit is the primary object of this invention to simplify the means ofcontrolling the amplitude of movement of the valve 6 or a valvecorresponding thereto. In order to accomplish the desired result Iprovide a threaded cap member 15 removably secured on the upper end ofthe housing 1 and depending from the curved spider arms 16 is aninwardly extending projection or lug 17 which may act as a stop for theunseating movement of the valve.

It will be observed that the cap member comprises a ring having spiderarms 16 and the depending sto-p lug 17 all integrally formed. The spacesbetween the arms forming sight openings so that the position of the stopmember 17 with respect to the valve will be observed, it being apparentthat when the internally threaded cap is screwed upon the externalportion 18 of the housing the stop 17 may be adjusted with respect tothe valve to control its amplitude of movement.

It is an important feature of the invention that the amplitudecon-trolling means is adapted to be associated with known types of flushvalve mechanisms now on the market and it will therefore not benecessary to re-arrange the construction of ythe flush valve mechanismin order to include the advantages of my invention.

It will be apparent that by so constructing the cap, sight openings areprovided and the lug 17 will be integral but preferably axially disposedwithin the cap and the housing, that a very inexpensive. means isprovided for controlling the amplitude of movement of the valve and thatsuch cap may be easily associated with known types of flush valvemechanisms.

What I claim and desire to secure by Letters-Patent is:

1. In combination with a flush valve mechanism having a reciprocatoryvalve of an internally threaded cap on the end of the housing for thevalve having :sight spider ari'ne providing sight openings beopeningstherein, and an integral inwardly tween theni and an inwardly projecting10 projecting stop lug carried by the cap so rigid stop member connectedto the spider that the position of the cap with respect to arms in theirpoints of intersection.

5 the housing will determine the amplitude ln testimony whereof I mysignaoi' nioveinent of the valve. ture.

2. A stop cap for valves comprising an internally threaded ring havingcurved JAMES C. RYAN.
